JAR OPENER Filed Feb. 28, 1951 VENTOR s I ATTORNEY Patented Jan. 10,1933 UNITED STATES PATENT OFFICE The object of this invention is toprovide an improved means for removing the cover of a fruit jar,assuming that the cover of the jar fits over the neck of the jarthedevice being adapted for mounting in a stationary position, so that thejar may be turned by hand after the cover engages the opening device,and the slipping of the jar, or false movement of the implement will beavoided.

A further object is to provide in one form an implement or member fixedin a stationary position and having segmental gripping means thereon,and an element pivoted to the member first named and also havingsegmental means thereon, the two elements being complementary andcooperative in their action on the cap when the jar is rotated in a.left hand direction incident to the opening movement.

Withthese and other objects in view as will become more apparent as thedescription proceeds, the invention consists in certain novel featuresof construction, combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawing forming part of the appli- I, cation:

Figure 1 is a view showing the device inedge elevation, the upperstationary element being dotted, and a fragmentary portion of a jar fromwhich the cap is to be removed is also dotted.

Figure 2 is a bottom plan view of the structure appearing in full linesin Figure 1.

Figure 3 is a section on line 33 of F igure 2.

Figure 4: is a bottom plan view showing a modification in which twosegmental elements are movable angularly about an axis ofiset from eachother.

Figure 5 is a section on line 5-5 of Figure 4.

The jar is designated 10 and the threaded neck portion is shown at 11.The jar opening device includes a plate member 12 having apertures 13and 14: therein permitting it to be secured in a stationary position andprefw erably to. the under side of the sink drain board or the like,whereby the jar, in upright position will be held in the position ofFlgure 1 and applied as shown with reference to the stationary elementof the opening devices.

Element 12 is provided with a downwardly turnedsegmental flange 15, andthe latter has tooth llke members 16 on the inner side thereof. Anysuitable construction may be employed in this connection.

A pivoted element includes the plate member 18, the latter being securedby means of pivot 19 to element 12, and member 18 is vprovided with thesegmental flange 20 having tooth like portions 21 on its inner concavesurface. The flanges of the stationary and pivoted members arecomplementary, with reference to the curvature, and the opposite sidesof a jar cap are gripped when the jar is given a movement toward theleft producing a slight angular movement of pivoted member 18, incidentto the gripping action. This result is produced because of the positionof the pivot 19 with reference to the approximate center of the openingbetween the segmental jaws.

A modified form of the device is illustrated in Figures 4 and 5, and asingle plate 25 which may be of rectangular configuration is consideredto be in a stationary position, apertures for the application of screwsbeing shown at 26 and 27. The gripping elements may be considered asjaws and each includes a se ental flanged member, the gripping portionsof which are designated 28 and 28. These members are mounted forrelative angular movement, and the pivots 29, 29 are eccentric withreference to the approximate center of the opening between the jawscomprising the segmental elements.

The jar is introduced between the jaws, in substantially the mannerbefore indicated and a left hand turn produces a slight angular,movement between the jaws pivoted oficenter, and the top beingeffectually held, the rota- 95 tion of the jar will, of course, resultin the loosening of the cap.

Whatis claimed is:

A device of the class described, com rising an eccentri'cally pivotedplate member aving so ental means thereon adapted to grip one si e of a.jar top, and another plate member having segmental means thereoncomplementary to the first named means and piv- 5 oted for eccentricmovement with respect thereto, the pivot points for the plates beingoppositely located with reference to a. center from which the curvesrepresented by the complementary segmental means are struck.

In testimony whereof I afiix my si FRANK P. S

ature.
